after 1860’s the railway systems has started to be used in urban transportation in the world. however, especially after the 1950’s, automobile usage has been increased quickly. thus the dense of transportation has started to move from railway systems to the ones with rubber tire vehicles in istanbul. traffic density in urban transportation has started to be experienced since 1950 with the incre...

In this paper, a socially responsible supply chain consisting of one supplier and one retailer is proposed. The supplier decides on replenishment cycle multiplier and the retailer invests in corporate social responsibility (CSR) and decides on the order-up-to-level under a periodic review replenishment policy. The retailer’s decisions impact on the supplier’s probability as well as the supply c...

car-following models are among the most important components of micro traffic flow simulation which is studiedby transportation experts to evaluate new applications of intelligent transportation systems. until now, several carfollowingmodels have been proposed. an obvious disadvantage of the former models is the great number of parameterswhich are difficult to calibrate. in this paper, a car-fo...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

This article deals with the intermodal transportation problem for the commodities delivery between different locations. The time – dependent shortest path planning, in which the travel time along each arc is a known function of the departure time along the arc, is a very important problem and arises in many practical application such as a routing system of a container used in the time – depende...

The share of intermodal transportation, which is often considered as a sustainable transportation alternative, rather low compared to road transportation. There are several reasons for this situation, including the increased need coordination scheduled transport services and reduced reliability chains in case disruptions. In regard, developing an advanced algorithmic approach can help handle re...

This study introduces space, transportation, and money into an economic growth model. Growth theory neglects the importance of transportation on economic growth and transportation economics fails to properly explain how changes in transportation conditions (such as technological improvement, infrastructure investment, and oil prices) affect long-term economic growth. By proposing a growth model...
